Abstract

Ultra precision machining on a CNC diamond turning machine J. Lamb Precision Engineering Laboratory, A WE Aldermaston, United Kingdom Abstract This paper describes the features and operation of the Diamond Turning Facility at AWE Aldermaston. Examples are given of some of the sophisticated sub- systems and constructional features of the machine along with the back-up equipment needed to run a facility of this type. The capability of the machine is discussed and Finally some typical work examples, along with results, are shown, demonstrating the precision and variety of work carried out on the machine. 1 Introduction AWE's Diamond Turning Facility consists of the Ultra Precision Lathe or U.P.L., arguably one of the most accurate lathes of its type in the world, housed in an environmentally controlled room and supported by sophisticated setting, testing and inspection equipment, and of course the specialist personnel required to successfully run a facility of this type.
